Installing the 16-Port asynchronous adapter

The 16-port asynchronous adapter fits into a single Micro Channel slot in the server. To install the adapter, use these steps.

Verify that all users are logged off the system and run the following command:
```
shutdown -F
```
When the shutdown command completes, turn the system power switch to the "off" position.
Open the server case and insert the 16-port asynchronous adapter into a free Micro Channel slot.
Attach the 78-pin D-shell connector from the 16-port interface cable to the 16-port adapter.
Put cover panels back on the system unit.
Push the system power switch to the On position. The system will recognize and configure the 16-port adapter during the boot process.

After the boot completes, log in using the root user ID and issue the following command to check the adapter availability:

lsdev -Cc adapter | pg

Only those adapters in the available state are ready for use by the system.

If the newly installed adapter is NOT available, then verify the following:

The adapter is installed correctly into the Micro Channel slot.
All necessary cabling is attached and fitted tightly into place.
Run the command: errpt -a | pg and examine the system error report for problems relating to the adapters.
Run the command: cfgmgr -v | pg. This command will attempt to reconfigure the adapter without rebooting. Watch the paged output for errors.
If running cfgmgr fails, a reboot will be necessary.
